  After the outbreak of the new crown epidemic in 2020, despite the doubled pressure on the construction work that is coming to an end, the builders of the Beijing Winter Olympics insisted on opening a new game in the changing situation, and their determination and confidence to win the final construction battle have always been firm.

  At the beginning of 2020, the National Snowmobile and Sled Center, which is the most difficult to design and the most difficult to construct in the Beijing Winter Olympics, overcomes difficulties such as poor communication and reverse jet lag, and promotes the construction through remote connection with foreign experts during the "war epidemic", becoming the Beijing Spring Festival The only construction project that did not stop during the period.

  At the end of 2020, the foreign ice maker of the National Swimming Center was unable to be present due to the epidemic. The Chinese team resolutely launched the second "water-to-ice conversion" and independently produced a curling track, which was four times more efficient than the first.

  "Despite the severe global epidemic in 2020, the 12 competition venues in the three major competition areas of the Beijing Winter Olympics, Beijing, Yanqing, and Zhangjiakou, will be delivered as scheduled at the end of 2020 in accordance with the preparation requirements. Beijing Winter Olympics Organizing Committee, Beijing, Zhangjiakou City The governments of the two places have worked hard to overcome various difficulties and ensure continuous and unabated efforts. The International Olympic Committee and many international organizations have spoken highly of this, and we express our heartfelt thanks!" Relevant person in charge of the Beijing Winter Olympics Organizing Committee Say.

  Commitment is inevitable, and completion on schedule is of great significance.

  There are 6 competition venues in the Beijing competition area, which is the largest in each competition area. However, under active promotion, the Shougang Ski Jump became the first newly completed competition venue for the Beijing Winter Olympics, and the National Aquatics Center became the first completed renovation of the Beijing Winter Olympics. , Wukesong Gymnasium has achieved the transformation and upgrading goal of "construction started and completed that year".

  The Yanqing competition area was constructed in the early stage under the "four nos" conditions of no water, no roads, no electricity, and no communications.

The conditions for the construction of the National Snowmobile Center are very difficult. The main track of the National Alpine Ski Center is located in the Xiaohaituo Mountain of Yanqing at an altitude of 2,198 meters. The wind and snow enhance the "Iron Army" style of the builders of the Beijing Winter Olympics.

  The sports competitions held in the three competition venues of the ancient poplar venues in the Zhangjiakou competition area are all projects that have been developed late in China, are relatively backward, and have relatively few talents.

The construction of venues opened up in "crossing the river by feeling the stones".

In November 2020, when the International Snow Federation experts pre-certified the national ski jumping center, they praised it as the world's unique ski jumping venue, and the construction of the ski jumping track is also the best in the world.

Technology leads

  Relying on the achievements of the country's modernization development, the Beijing Winter Olympics competition venues have a long-term perspective and are exquisite and insightful, embodying the key words of technology, wisdom, green, and frugality.

  ——Construction highlights are all difficult points, and China's scientific and technological strength breaks the problem.

As the only newly-built ice competition venue for the Beijing Winter Olympics, the National Speed ​​Skating Stadium has built the world’s largest single-layer two-way orthogonal saddle-shaped cable net roof. The scale is the largest in the world stadium, but the steel consumption is only a quarter of the traditional roof. One.

After applying the "technological construction" method, the steel structure of 8,500 tons and the curtain wall glass of different shapes can be prefabricated in the factory and assembled on site, and the construction speed and quality have been doubled; the national snowmobile and sled center gave up the high salary The practice of hiring foreign teams to take the road of independent innovation in China: the 1.9-kilometer track concrete was sprayed and poured at one time, 133 projects were applied for patents, and 105 were accepted and authorized.

  ——Venue operation is equipped with a "brain", and smart results will be fully unveiled.

Through the introduction of the "global digital twin system", "indoor and outdoor integrated positioning and navigation system", a network system based on the intelligent integration of "cloud-network-fog-terminal", "energy management system" and new "BIM operation and maintenance system" and other technologies It's like equipping the stadium with a "brain."

With a speed skating stadium with a "smart brain", athletes and spectators can enjoy positioning and navigation services through their mobile phones after entering the stadium, matching the best route to the destination, robots asking for directions, unmanned vending cars, virtual ice and snow sports, etc. This new scientific and technological achievement will be presented in a more complete form.

With the pace of the Winter Olympics approaching, the construction results of the "smart venues" of the competition venues will be fully unveiled.

  —— Give priority to green, environmental protection and ecology, and the construction of venues will impress the beautiful Chinese background.

For the first time in the history of the Winter Olympic Games, the Beijing competition area used a more environmentally friendly carbon dioxide refrigerant, which was 30% more efficient than traditional refrigeration methods; the Yanqing competition area first conducted an environmental background investigation before the start of construction, and sustainable development became a prerequisite for venue construction and no discussion The iron rule of the Beijing Winter Olympics is also the first Olympic Games in the history of the Olympics to use green and clean electricity.

The Zhangbei Rou direct power grid project connects the wind and solar power in the Zhangbei area to the Beijing power grid. It is estimated that approximately 22.5 billion kilowatt-hours of clean energy will be delivered every year to achieve 100% green power supply for the Beijing Winter Olympics venues.

  —— Adhere to the principle of economy, avoid extravagance and waste, and use the most frugal way to host the Winter Olympics.

The Beijing Winter Olympics venues strictly control the space requirements, and try to make "subtraction" in terms of demand under the premise of ensuring that the event is held.

Fully renovate existing venues for the 2008 Olympic Games such as the National Swimming Center, National Stadium, Capital Stadium, and Wukesong Sports Center. This not only effectively reduces construction investment, but also allows the Summer Olympics venues to welcome the Winter Olympics with a new lease of life and expand diversified post-match management capabilities.

Pursuit of excellence

  The "Proposals" of the "14th Five-Year Plan" clearly stated that it is necessary to "make good preparations for the Beijing Winter Olympics and the Paralympics", and at the same time include building a "sports power" and "healthy China" in the long-term goal of basically realizing socialist modernization by 2035.

  If sports are strong, China will be strong, and national sports will flourish.

The Beijing Winter Olympics competition venues planted the "seeds" for the leap-forward development of my country's ice and snow sports.

The National Alpine Ski Center, the National Snowmobile and Sled Center, and the National Ski Jumping Center make up for the gaps in the construction of related sports venues in China. Finally, professional sports teams can train at a high level "at their doorstep" without having to "wander around" around the world to find venues.

  "Northern ice expands from the south to the west, expands from the west to the east," and China's strategy for advancing the development of ice and snow sports is inseparable from the extensive participation of the masses.

The venues for the Beijing Winter Olympics are planned to be used after the games at the beginning of the construction and renovation, and will better satisfy everyone's yearning for winter sports in the future.

The newly-built ice surface of the Beijing competition area can be opened to the public after the game. The National Speed ​​Skating Hall has a huge 12,000 square meter all-ice surface. After the game, it can receive 2,000 tourists and carry out various ice sports.

  Around the construction of the Beijing Winter Olympics competition venues, the construction of related supporting infrastructure has also been completed simultaneously, and the results of regional coordinated development have been shown.

The Shougang Ski Jump was originally an ordinary track, but through the integration of urban history and development goals, it was placed in the planning and construction of a century-old industrial heritage park, which led to the urban rejuvenation, transformation and upgrading, and has become a "net celebrity check-in site"; Zhangjiakou City Around the construction of competition venues to create an ice and snow industry gathering area, the ice and snow town of Chongli is plugged into the wings of the Winter Olympics to help the regional economy take off.

  The Beijing Winter Olympics, which release passion, unite people's hearts, and pursue excellence are worth looking forward to, but right now, half of 90 people can travel a hundred miles.

"With the completion of the Beijing Winter Olympics competition venues, we will make every effort to ensure that all venues and infrastructure construction tasks are completed as planned, and we will do our best to ensure the testing activities of the competition venues, in-depth preparation of venue facilities, and focus on promoting the operation of the venues. , And strive to contribute to the world a wonderful, extraordinary and outstanding Olympic event." said the relevant person in charge of the Beijing Winter Olympics Organizing Committee.
